苹果矮化中间砧SH40激素含量及生长素转运蛋白基因pinl表达
The content of hormone and auxin transport gene pin 1 of SH40 as the interstock of apple
摘要
Abstract
Both rootstock SH40,Malus micromalus and scion-rootstock combinations Fuji/SH40/Malus micromalus,Fuji/Malus micromalus were used as the materials in this experiment,Both IAA and ABA were measured by HPLC in the bark of different materials.qRT-PCR（quantitative realtime PCR） were also used to search for the difference of expression of pin1 gene.Our aim was to explore the relationship between the content of hormone,the expression of pin1 gene and the possible dwarfing factors of SH40 as the interstock of apple.The results showed that the ratio of ABA/IAA was remarkable higher in the dwarf trees than the vigorous controls.In graft combination Fuji/SH40/Malus micromalus,the content of IAA in the bark of the interstock was much lower than the scion,which might be due to the significant lower expression of IAA-transporting protein gene pin1 in the bark of the interstock.关键词
